LOUIS, MISSOURI, ASSIGNOR TO ME'IEUDY AUTOMATICLIGHTER 00., OF EAST ST. LOUIS, ILLINOIS, A CORPORATION OF ILLINOISIGNITION DEVICE FOR GAS BURNE'BS Application filed November 11, 1929.Serial No. 406,119. 7

This invention relates to an ignition device for burners of gas stoves.An object of this invention is to provide an-automatic ignition devicefor a gas stove burner which is simple, economical and safe. Other andparticular objects will appear from the detailed description whichfollows taken in connection with the accompanying draWings,.in-fwhichFig. 11 is a plan view of the burner, its

connections, the ignition device, and its connections. Fig. 2 is across-sectional view taken on line 22 of Fig. 1. Gas is supplied througha manifold 1 by a valve 2 through an air mixer 3 to the burner '4. Theburner *inay be of any ordinary construction having holes 5' in its topwall and may comprise a plurality of arms, as specifically illustratedin the drawin s.

One of the arms is elon ate as shown at 6, to form a connection wlth theinterior of a pilot housing 7 in which constantly burns a lighted pilotjet 8 supplied with fuel through the plpe 9 from the manifold 1.

The pilot housing 7 has one or more horizontal outlets 10 to connectwith one or more burner extensions 6. .An annular baflie plate 11 issituated above the pilot jet 8 and below the outlets 10. Air is admittedto the pilot jet to form a combustible mixture through a suitableorifice at the bottom' of the housing shown'at 12.

The burner extension 6 is connected to the pilot housing 7 bytelescoping its end into a suitable female portion in the housing. The

burner extension 6 is provided with holes 13 in -its to wall of smallerdimension than the regular urner holes 5. Its end wall is closed 0except for a horizontal opening 14 directed towardthe pilot housing 7and crossing a vertical orifice 15 between the end-wall of the extension6 and the pilot housing 7.

' The pilot jet 8 is kept burning continuously. When it is desired tolight the burner- Combustion occurs, the flame running back to the hole14 in the end wall, upward through the vertical orifice 15, igniting the=mixed gases coming through the holes 13 in the extension, and thenceover the entire top surface of the burner. As soon as this has occurred,the gas will be consumed to such an extent that no appreciable amountescapes on through the hole 14, and what little does pass through thathole is consumed by a flame which passes upwardly through the verticalorifice 15. The pilot light resumes its normal condition and the pilothousing is otherwise 5 free from flame.

While asshown, the pilot housing is connected to only one burner, itwill be obvious that it may be connected to as many as desired,ordinarily four.

From the foregoing, it will be apparent that an ignition device has beenprovided which is automatic, simple of construction, and safe andefficient in o ration.

Various changes may made in the details of construction within the scopeof the appended claims"without departing from the spirit of theinventlon. e I claim: I v

1. In combination with a as burner so adapted to receive a icombustib emixture, means for. igniting the same comprising a pilot jet, a housingtherefor, an extension of the burner' 'having a series of spaced holesthrough its wall, and a member connecting said extension and housing andhaving'an orifice positioned and adapted to permit the escape of flameto ignite the combustible IIllX- ture after passing through said holes.

2. In combination -.witlr a gas burner 00 adapted to receive acombustible mixture, means for igniting the same comprising a pilot jet,a housing for said jet, an extension of the burner having a series ofspaced holes through its wall, and a connecting element between saidhousing and said extension communicating withthe burner through a holein the end wall of the extension and having la1 llateral orifice incommunication with said 3. A gas burner having an extension with aseries of spaced holes through its wall, a pilot jet, a housing for saidjet, an element connecting said extension and said housing and having alateral orifice positioned and adapted to permit the communication offlame therefrom' to the extension at said holes.

4. In combination with a gas burner adapted to receive a combustiblemixture, means for igniting the same comprising a pilot jet, a housingfor said jet, an extension on the burner having a series of spaced minorholes through its wall, and a connecting element between said housingand said extension communicating with the burner throu h a constrictedopening in the end wall of t e extension and having a lateral orifice incommunication with said opening.

5. In combination with a gas burner adapted to receive a combustiblemixture, means for igniting the same including a pilot jet, a housingtherefor, an extension of the burner having a series of spaced holesthrough its wall, and a connecting element integral with the extension,the end of said element telescoping into a suitable female portion inthe housing.

6. In combination with a gas burner adapted to receive a combustiblemixture, means for igniting the same comprising a pilot jet, a housingenclosing said pilot jet, an extension of the burner having a series ofspaced holes through its upper wall and havlng an end wall provided witha hole therethrou h, and means including said hole in said end wallforming a communication from said extension to said housing.

7. In combination with a gas burner adapted to receive a combustiblemixture, means for igniting said mixture comprising a pilot jet, ahousing enclosing said jet and havin an orifice in its lower end foradmitting a1r into the housing, an extension of the burner having aseries of spaced holes through its upper wall and having an end wallprovided with a hole therethrough, and a member connecting saidextension and said housing and having an orifice positioned and adaptedto permit the escape of flame to ignite the combustible mixture aftersaid mixin said burner.

8. In combination with a gas burner' adapted to receive a combustiblemixture.

.an orifice located and adapted to permit the escape of flame to ignitethe combustible mixture after said mlxture passes through said firstnamed holes in said extension.
